Abstract
A sensor for a transmission-shift control of a motor vehicle is described. The sensor is connectable to a supply voltage (Vs) and to ground (GND). The sensor generates a signal voltage (Vout). The signal voltage (Vout) may assume two signals (high, low), both signals (high, low) being different from the supply voltage (Vs) and from ground (GND).
Claims5
A sensor for a transmission-shift control, the sensor being connectable to a supply voltage and to ground, and the sensor being configured to generate a signal voltage, the signal voltage including one of a high signal and a low signal, each of the high signal and the low signal being different from the supply voltage and from ground,
- wherein the sensor is configured to define a voltage range for the high signal and a voltage range for the low signal, the voltage ranges of the high signals and the low signals being defined by an upper limit and a lower limit, respectively,
- wherein the sensor is configured to recognize the signal voltage as the high signal if it is between the limits of the voltage range for the high signal, and to recognize the signal voltage as the low signal if it is between the limits of the voltage range for the low signal,
- wherein one or more of the limits are dependent on and a function of the supply voltage, and
- wherein an alteration of the supply voltage causes an alteration of one or more of the limits.
